VOL. XLIV.] PHILOSOPHICAL TRANSACTIONS. IQS 



He continued languishing, and in extreme pain all over his body, even his 

 fingers and toes, from this day to the 24th of July, not being able to bear being' 

 touched in any part of his body or limbs, some days before his death, which was 

 on that day, being 64 days since the commencement of this course : in which 

 time he took 8 1 doses of the lixivium, being one day with another (till he left off 

 entirely, which was 24 days before he died) about 20 drops a day. 



During the course, his water was generally thick and muddy; though when in 

 great pain, sometimes clear and high coloured. In about 3 weeks after he began, 

 there was a great deal of that tough fetid mucus in his urine, which continued till 

 he left off taking the lixivium, and then decreased considerably, till a fortnight 

 before his death, when it entirely disappeared, and his urine had no smell or taste, 

 and came away involuntarily. 



On straining and filtrating the urine, Mr. C. often found little scaly bits, very 

 small, which, when dry rubbed, became an impalpable powder. After he left ofF 

 the medicine, Mr. C. could never find this in the urine, though he searched very 

 carefully. His diet the whole time was chiefly spoon-meat; now and then a little 

 meat, but very seldom ; and he had but little appetite when he began, and was 

 very weak. 



On opening the body Mr. C. found his kidneys very sound, and neither stone 

 nor gravel in them: but in his bladder there were 214 stones; the 2 largest about 

 the size of nutmegs, the others gradually less, to the size of a pea, and smaller, 

 but each whole, not pieces. They were of a soft chalky substance and colour, 

 and weighed all together 6 oz. 2 scr. 4 grs. Avoird; besides which, there were 

 several small scales, such as he found in his urine. The other viscera had no- 

 thing remarkable. The quantity of small chalky and scaly bits and powder that 

 he could save out of the urine, was about as much in 24 hours as would well 

 cover a shulling ; and perhaps there might be as much more lost in his urine, 

 when at stool, and on the sides of the pot and urinal. 



Further Experiments and Observations, tending to illustrate the Nature and 

 Properties of Electricity. By William Watson, Apothecary, F. R. S. 

 N<'478, p. 41. 



As water is a non-electric, and of consequence a conductor of electricity, there 

 was reason to believe that ice was endowed with the same properties. On making 

 the experiment, the conjecture was verified; for on electrifying a piece of ice 

 wherever the ice was touched by a non-electric, it flashed and snapped. A piece 

 of ice also, held in the hand of an electrified man, as in the beforementioned pro- 

 cesses, fired warm spirit, chemical vegetable oils, camphor, and gunpowder pre- 

 pared as before. But here great care must be taken, that by the warmth of the
